Allele frequencies at all variable loci for the four taxa diagnosed by stepwise PCO.

<p>For polymorphic loci, the frequencies of all but the rarer/rarest alleles are expressed as percentages and shown as superscripts (allowing the frequency of each rare allele to be calculated by subtraction from 100%). The maximum sample size is shown in brackets for each taxon. * Loci diagnostic for distinct clades. The following loci were invariant: <i>Argk</i>, <i>Enol</i>, <i>Fdp</i>, <i>Gp1</i>, <i>Gp2</i>, <i>Ipp</i>, and <i>Pk</i>.
